[Serusers] LCR failure syntax

[Matt Schulte]

Ok, I've checked over my config and am going bananas. I cannot get a
"failover" scenario working. The first LCR load_gw is fine however
whenever a call fails (in this instance I am generating a 404) it never
sees the second priority. Thoughts?

I Dial 636561XXXX
I checked my logs, everything goes through just fine, get the 404 (per
failover test), it gets caught by the failure if statement and spits out
no more gateways..

lcr table (accounting for e164 and non)
+------------+----------+--------+----------+
| prefix     | from_uri | grp_id | priority |
+------------+----------+--------+----------+
| +1636      | %        |      2 |        1 |
| +1636      | %        |      1 |        2 |
| 636        | %        |      2 |        1 |
| 636        | %        |      1 |        2 |
+------------+----------+--------+----------+

route[99] {

t_on_failure("2");
if(!load_gws())
                {
                sl_send_reply("500", "Internal server error, unable to
load gateways");
                break;
                }
        log (1, "Running next_gw\n");
        if(!next_gw())
                {
                sl_send_reply("503", "Service not available, no gateways
found");
                xlog("L_INFO", "<%ru> <%br>\n");
                break;
                }
        xlog("L_INFO", "Time %Tf RURI <%ru> \n");

		t_relay();
		break;
}

failure_route[2]
{
   log(1, "Hit failure route 2\n");
   if(method == "INVITE" && t_check_status("408|500|503|480|400|404"))
   {
        xlog("L_INFO", "NOTICE: Hit failure 2 and error status code\n");
     if (!next_gw())
     {
         xlog("L_INFO", "ERROR: No more gateways for LCR failover
dropping call\n");
       t_reply("503", "Service not available, no more gateways");
       break;
     }
     t_on_failure("2");
     # ...
     t_relay();
   }
}

something like this....

route[8] {
   if (!load_gws()) {
      sl_send_reply("500", "Server Internal Error - Cannot load
gateways");
      break;
   };
   if (!next_gw()) {
      sl_send_reply("503", "Service not available - No more gateways");
      break;
    };
         t_on_failure("4");
         if (!t_relay()) {
         sl_reply_error();
         };
}

failure_route[4] {
         if (!next_gw()) {
                 t_reply("503", "Service not available - No more
gateways");
                 break;
         };
                  t_relay();
                  break;
}
